Google absurdities

I have a few websites based on Google Sites. In one I have links to the other sites. But when I click on such a link a message stating a redirection had taken place flashes over my screen. But I arrive at the correct page. I had a look what really was present in the link, and indeed, its content was completely different from the URL of the site it should bring me to. It looks like a query. Is it something to analyse what you are doing?
